Junior Bake Off is back for a brand new 15-part series, hosted by Sam and Mark. Judges, top international chef Allegra McEvedy and executive pastry chef Graham Hornigold test 40 of Britain's best young bakers over a series of 10 heats followed by a knock-out week of finals. In each heat four bakers will face two challenges, the technical and the show-stopper, before one of them wins through to the next round.

Entering the hallowed Bake Off tent, the first four junior bakers - Alyth, Harrison, Kiah and Matthew - have their baking knowledge tested when they're asked to follow a surprise recipe for strawberry shortcake stacks. The shortcakes need to be evenly baked and sandwiched together with cream and strawberries without falling over, so who will demonstrate precision and a cool head to make it into the top two? Following this they have the chance to express themselves through their baking with a show-stopping pinata cake, which should cascade with delicious treats when cut open. Show less
